Primary Outcome Measures:
  • Latency to Sleep Onset After Middle-of-the-Night Awakening at Baseline [ Time Frame: Weeks -1 to 0 ] [ Designated as safety issue: No ]
    Time was recorded by study participants using a telephone interactive voice response system (IVRS) to answer the question: How long did it take you to fall asleep after taking your study medication?

  • Latency to Sleep Onset After Middle-of-the-Night Awakening During Double-blind Treatment [ Time Frame: Weeks 1 to 4 ] [ Designated as safety issue: No ]
    Time was recorded by study participants using a telephone interactive voice response system (IVRS) to answer the question: How long did it take you to fall asleep after taking your study medication?


Secondary Outcome Measures:
  • Subjective Total Sleep Time Following Middle-of-the-Night Awakening at Baseline [ Time Frame: Weeks -1 to 0 ] [ Designated as safety issue: No ]
    Total sleep time in minutes after waking in the middle of the night. The values were recorded by participants using a telephone interactive voice response system (IVRS) to answer the question: After you fell back to sleep, how long did you sleep until you woke up this morning?

  • Subjective Total Sleep Time Following Middle-of-the-Night Awakening During Double-blind Treatment [ Time Frame: Weeks 1 to 4 ] [ Designated as safety issue: No ]
    Total sleep time in minutes after waking in the middle of the night. The values were recorded by participants using a telephone interactive voice response system (IVRS) to answer the question: After you fell back to sleep, how long did you sleep until you woke up this morning?

  • Subjective Number of Awakenings Following Middle-of-the-Night Awakening at Baseline. [ Time Frame: Weeks -1 to 0 ] [ Designated as safety issue: No ]
    Number of awakenings following middle-of-the-night awakening were recorded by study participants using a telephone interactive voice response system (IVRS) to answer the question: After you fell back to sleep, how many times did you wake up again before waking up in the morning?

  • Subjective Number of Awakenings Following Middle-of-the-Night Awakening During Double-blind Treatment [ Time Frame: Weeks 1 to 4 ] [ Designated as safety issue: No ]
    Number of awakenings following middle-of-the-night awakening were recorded by study participants using a telephone interactive voice response system (IVRS) to answer the question: After you fell back to sleep, how many times did you wake up again before waking up in the morning?

  • Subjective Wake Time After Sleep Onset Following Middle-of-the-Night Awakening at Baseline [ Time Frame: Weeks -1 to 0 ] [ Designated as safety issue: No ]
    The number of minutes subjects reported being awake after onset of sleep following middle-of-the-night awakening during the baseline period. Values were recorded using a telephone interactive voice response system (IVRS) to answer the question: Considering all of these awakenings (after taking study medication and returning to sleep), how long were you awake from the time you went back to sleep after dosing until you got out of bed this morning?

  • Subjective Wake Time After Sleep Onset Following Middle-of-the-Night Awakening During Double-blind Treatment [ Time Frame: Weeks 1 to 4 ] [ Designated as safety issue: No ]
    The number of minutes subjects reported being awake after onset of sleep following middle-of-the-night awakening during double-blind treatment. Values were recorded using a telephone interactive voice response system (IVRS) to answer the question: Considering all of these awakenings (after taking study medication and returning to sleep), how long were you awake from the time you went back to sleep after dosing until you got out of bed this morning?

  • Morning Sleepiness Rating Following Dosing Post Middle-of-the-Night Awakening at Baseline [ Time Frame: Weeks -1 to 0 ] [ Designated as safety issue: No ]
    Morning sleepiness was assessed using a 9-point sleepiness scale (1=very sleepy to 9=wide awake and alert). During the baseline period, all participants received placebo.

  • Morning Sleepiness Rating Following Dosing Post Middle-of-the-Night Awakening During Double-blind Treatment [ Time Frame: Weeks 1 to 4 ] [ Designated as safety issue: No ]
    Morning sleepiness was assessed using a 9-point sleepiness scale (1=very sleepy to 9=wide awake and alert). Values are from dosing nights during double-blind treatment.
